Study on Electrocatalytic Oxidation Degradation of Phenol by Ti-based Sn-Sb-Pb Oxide Coating Anode

Abstract

Ti-based Sn-Sb-Pb oxide coating electrode was prepared by high temperature thermal oxidation method. The obtained electrode has high electrocatalytic activity and good stability. The surface morphology, oxygen evolution potential and service life of each electrode were examined by scanning electron microscope, oxygen evolution potential measurement and accelerated life test. Phenol was taken as the target organic matter. Under the conditions of applied voltage 8V and water temperature 30°C, the COD removal rate of 100mg/L phenol simulated wastewater was electrolyzed, and the COD removal rate of phenol solution could reach 71.1% in 60min.
